To alt w/wnt it may concern:

Be it known that I, JOHN R. BOONE, a citizen of the United States,residing at Nashville, in the county of Davidson and State of Tennessee,have invented certain new and useful Improvements in Hydrocarbon Burners, of which the following is a specification.

My invention relates generally to hydro-- carbon-burners adapted to heatwater to gensubburner, which in turn heats the vaporizer through whichthe gasolene or other fuel passes to the main burner. In burners'of thisclass'the initial burner is only used when starting, which latter servesto. vaporize the fuel forthe pilot or subburnen whic'h is kept"constantly burning and serves not only to vaporize the fuel for themain burner, but also to maintain su'flicient heat to keep" up steam ata low pressure in the boiler when the supplyof fuel in the 'main burneris sus- The'object of my invention is to simplify the construction ofsuch burners, render their adjustment easy, andmake them readilyremovable or" separable for inspection or repair. I

In carrying out my invention I perma nently attach the case of thesubburner to a suitable part of the main burner, and the sub burner andinitial burner areseparable' from the case, so that they may be readilyWithdrawn for inspection, adjustment, or repair. The subburner is alsoreadily detachable from the fuel-supply pipe, and the sprayingnozzle iseasily accessible or may be easily removed. The initial 'burner'is inthe form of a cup which surrounds the lower member of the subburner, andthis is arranged to heat a coil which surrounds the upper portion of theupper member of the subburner and which is made readily detachable fromthe subburner and from the supply-pipe. The fuel which supplies thenozzle of the subburner passes through the coil.

In the accompanying drawings, Figure 1 is a perspective view of asteam-generator and main burner of well-known construction with myimproved subburner and its accessories applied. Fig. 2 shows a verticalcentral section of the same- Fig. is a detail view in perspective,showing a particularly how 1 the casing I of" the subburner ispermanently at tached to themain burner a'nd how t'he subburner and fitsaccessories areremovable from the easin ""Fig. '4 shows-a vertical cen-F connected therewith.

I have shown myimprovements applied to o 5 a main burner and generatorof 'awell known ki d; v A indicates the coil of wate'r pipe'of thegenerator, and B the'main burner for heating tral sectionthrough thesubburner and "parts it. 'This 'burner'is'shown asconsisting-of achambered plate having on itsupper side annular perforated ribs 1),threugh which the. vaporized. fuel passes; 'The vaporizer C is also ofwell-knownconstruction. I This vapor-izer is connected with the interiorof the burner B by a pipe 0 and with the fuel-supply pipe D byapipecAjvalve 'cZ-c'ontrols the'-' admission of fuel to the vaporizer C.

1 My improved'subburner is contained within a case E,permanently'attached tothe main burner. This case-ispreferablycylindrical' and at its lower end on diame'tricallyj oppositesides is formed with right-angled slots c to receive the stud e of thesubburner,

-'W'ith'wh'ich{ it formsa bayon'et 'joint. The 8 5 subburner has twoprincipal parts and G,

which I call the -"up'per" and flower mem bers. The lower member F has acentr'al'verticalpassage f throu gh'it, and at its upperend it carries aspraying-nozzleH-Q The-supply 9o 1 of i'uel'through the, passage-f iscontrolled by a needle valve h, and'the" fuel' 'passes totlie 'i passagef, through a channel), extending diagonally upward through abossK'."Surrounding the central-portion of the lower member is a cup I, whichconstitutes the initial burner and to which fuel is supplied through thechannel, passage and-nozzle H in'the manner hereinafter explained.- Theupper member G comprises a tubular stem g and an upper enlargement,head, or cup 9, into which the fuel is sprayed and which contains aspreader J. The upper member G is supported on a yoke L. Its tubularstem g fits tightly in the top of the yoke, and the yoke has an annularbottom portion Z, which rests on the cup I and which is connected withthe top portion by uprights Z. The lower member F is clamped to the cupI by means of a nut I, and when so clamped 'the 1 1o yoke L is heldfirmly in place by reason of the engagement of the boss K with the base1 of thel yoke in the manner indicated in Figs. 3 an 4.

The cup I is provided with a tubular threaded boss M, which is adaptedto be connected with the fuel-supply pipe, and this threaded bossconnects with another boss N above it, which has a detachable'connectionwith one branch 0 of a coil 0. The other branch 0 has a detachableconnection with the tubular boss K. The coil 0 surrounds the spreader Jabove the subburner.

Normally the subburner and its accesso ries are contained within thecase E and locked thereto in the manner indicated in. Figs. and 2; but,if desired, by merely un-i coupling the threaded boss M from thesupply-pipe N the subburner may be detached from the casing by turningthe studs 6 in the slots 6 and se arating the parts in the ordinary way0 operating a bayonet -joint. While I have shown a bayonet-joint, other:connections may be used. When the burner is thus detached, it may becleaned, inspect-i ed, orv repaired. The coil O may be easily: detachedby uncoupling the unions 0 T he nozzle H may obviously be easilydetached and, if necessary, thrown away and replaced by a new one, orthe old nozzle may be easily cleaned.

.When starting up for the first time, the valve (Z may be closed and thevalve h is opened, so that fuel may pass through the boss M, coil 0,passage f and f, and through the nozzle H. The fuel which at this timepasses through the nozzle is not vaporized, but flows over into the cupI. When this fuel is ignited, it heats the fuel in the coil 0 andvaporizes it, so that thereafter the fuel that emerges from the nozzle His in the form of avapor and as such burns at the spreader J. Preferablyafter the cup I is supplied with a sufiicient amount for the initialburner the valve h is closed and the fuel in the cup I ignited, so as toheat properly the fuel in the coil 0. Then the valve h may be opened andthe fuel in the form of a vapor and under pressure will emerge from thenozzle H and ignite. Thereafter the fuel passing through the coil 0 isheated by the subburner, the initial burner of course being no longeremployed. The subburner heats the vaporizer C, that supplies the mainburner. The main burner may be shut off from time to time, while thesubburner is kept constantly burning and maintains vapor in thevaporizer C, so that the vehicle may be started up quickly wheneverdesired.

By my improvements 1 have produced a very eflicient subburner and onewhich is extremely simple and may be applied to various kinds or typesof main burners.

It will be observed that only one valve is employed to regulate thesubburner, and the parts are readily detachable and may be cleaned,repaired, or replaced with great facility.

I claim as my invention- 1. The combination of a main burner, a

casing open at the bottom and permanently attached to the main burner, acup constituting an initial burner and having a detachable connectionwith the casing at its lower end, the lower member of the subburnerdetachably connected with the cup, and carrying a spraying-nozzle, theupper member of the subburner, means for supporting it on the cup orinitial burner, a coil surrounding the upper member, and connected withthe spraying-nozzle, a fuel-supply passage with which the coilis alsoconnected, and a fuel-supply pipe detachably connected with. the coil,the arrangement being such that all parts of the subburner are supportedon the cup or initial burner and are detachable therewith and removabletogether through the bottom of the fixed casing.

2. The combination of the lower member of the subburner, a cup orinitial burner surrounding it and detachably connected there with, theupper member of the subburner, the yoke resting on the cup clampedthereto and supporting the upper member, a nozzle between the twomembers, a vapor-coil surrounding the burner, a supply-pipe to which thecoil is detachably connected, a boss on the lower member of the burnerand a detachable connection between the boss and the coil.

In testimony whereof I have hereunto subscribed my name.

JOHN R. BOONE.
